Visual Signaling and Carbon Monoxide (CO) Alarms
Section 6.9.4.2 (via related sentences) mandates specific requirements for visual signaling components in sleeping rooms or combined living/sleeping areas. Key standards include:
- Luminous Intensity: A minimum of 175 cd is required for visual signaling components to ensure occupant safety.
- Interconnection: While components do not need integrated battery backups or synchronized flash rates within a dwelling unit, they must be interconnected with the CO alarm.
- Installation Height: CO alarms must be installed at the manufacturer’s recommended height or, failing specific instructions, on or near the ceiling.
Ash Storage and Fireplace Compliance
Safety in solid-fuel burning installations is governed by strict material requirements:
6.9.4.1 Ash Storage Bins
All ash storage bins must be constructed of noncombustible materials. Every opening must be secured with a tight-fitting metal door and frame to prevent accidental fire spread.
6.9.4.2 Fireplace Construction
Under Section 6.9.4.2, all fireplaces must conform to the comprehensive requirements found in Section 9.22 of the OBC. This ensures structural integrity and proper ventilation for residential projects.
